About This Tool

This bcrypt converter tool allows you to securely hash passwords using the bcrypt algorithm with adjustable cost factor (work factor) for optimal security. You can also verify if a given plaintext matches an existing bcrypt hash. Bcrypt is a widely used password hashing function that incorporates salt automatically and is resistant to brute-force attacks. The tool works entirely client-side using JavaScript for maximum privacy.

How to Use

Enter the text you want to hash in the 'Text to Hash' field
Select a cost factor (default is 10, higher values are more secure but slower)
Click 'Generate Bcrypt Hash' to create a bcrypt hash
To verify a hash, enter the plaintext in the 'Text to Verify' field and the hash in the 'Bcrypt Hash' field
Click 'Verify Bcrypt Hash' to check if they match

Frequently Asked Questions

Find Quick Answers

What is bcrypt?

Bcrypt is a password hashing function designed by Niels Provos and David Mazières. It incorporates a salt to protect against rainbow table attacks and is adaptive over time to resist brute-force search attacks.

What is the cost factor in bcrypt?

The cost factor (or work factor) determines how many iterations the algorithm performs. Higher values increase security by making the hash computation slower and more resource-intensive, but also take longer to compute. Typical values range from 10 to 14.

Is my data secure with this tool?

Yes, all processing happens entirely in your browser using JavaScript. No data is sent to any server, ensuring complete privacy for your passwords and hashes.

Can I verify existing bcrypt hashes?

Yes, the tool includes a verification feature. Enter the plaintext password and the bcrypt hash, and it will tell you if they match.
